My Dart is 3350 and has been 6.25 @ 110 in the 1/8 on a 325 radial. It now has a 275 and has been 6.28. It has Viking double adjustables all around, 2C/10R on the rear and 16C/18R on the fronts on marginal tracks, all from full loose. The fronts have been revalved for no prep surfaces as I run mostly street car shoot out stuff. On well prepped tracks I lock the front shocks down, full tight.
